After a standout rookie season Reds left-hander Tony Cingrani has been on the disabled list for most of this season and now Mark Sheldon of MLB.com reports that he’s unlikely to pitch in September.

Cingrani has been on the Triple-A disabled list since late June with a strained shoulder and recently had to halt the start of a throwing program due to continued discomfort.

Cingrani has relief experience and using him out of the bullpen would require less time to build back arm strength, but at this point the Reds have much bigger worries with the 25-year-old southpaw than his status for the final month of 2014.

He has a 3.49 ERA and 190 strikeouts in 173 career innings, but walked 35 batters in 63 frames this year before the shoulder problems shut him down.
